For GloriousTrainwreck.com's Klik of the Month Klub #36 - http://www.glorioustrainwrecks.com/node/1316 - it's a 2 player game roughly like that old Crossfire toy/boardgame. Player 1 uses A and S, player 2 uses arrow keys left and right, and both players try to shove the green squares into their opponent's goal, first to ten wins.
A toy I made last year to entertain and possibly teach a 2-year-old - when the screen goes gray, click anywhere on it and start typing letters to see them sing and dance.
I recorded and remixed the sounds ahead of time but the core program was done in about 2 hours for a <a href="http://glorioustrainwrecks.com">Glorious Trainwrecks</a> KotMK game jam.
